ERF1 — Cucumis melo

Summary

MELO3C012896.2, also known as CmERF1 or ERF1, encodes an AP2/ERF domain-containing transcription factor on melon chromosome 5. The protein exhibits sequence-specific DNA binding and transcription coactivator activity, and localises to the nucleus. In melon, CmERF1 is associated with fruit ripening, ethylene and jasmonic acid signalling, cellular responses to drought and salinity, defence response upregulation, trichome formation, flower development, and red and far-red light phototransduction. The gene is linked to numerous traits including ethylene and auxin sensitivity, respiration and photosynthetic rates, disease tolerance, flowering time, root and hypocotyl morphology, and organ identity. Related genes in other species are associated with resistance to Botrytis cinerea, Pseudomonas syringae, and Fusarium oxysporum, as well as drought, salt, and heat tolerance, lateral root development, and anthocyanin synthesis.
